Hey Spock, you appear to be getting irrational and not using logic.
Where does the earlier version come in? The video shows the brightest to be a 3W LED not the 5W you refer to earlier in the thread. The video does not do a side by side comparison with a Tesco torch so why re reference it? If, as you say, they have upgraded the version that steelfan shows to the 3W that is shown in the video, then I reckon that makes them both 3W and comparable. If that is the case then £16 gets you 2 complete torches. No brainer.
